PROCESS OF WELDING AND REPAIRING.

Specification of Letters Patent.

Patented Nov. 13, 1917.

T 0 all whom it may concern:

Be it known that I, JAMES HEXRY REID, a citizen of the United States, residing at 352 Mulberry avenue, in the city of Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Processes of Welding and Repairing, of which the following is a specifica: tion.

This invention relates to the art of electric welding or repairing and means for performing same, and has for its object the utilizing of a plurality of electric currents and the provision of means for welding or 3 repairing structures by the action of alternatmg and direct currents of electricity, acting as a reciprocating are disposed between the article to be joined, welded, or repaired and the joinin or repairing substance or metal in an e and whereby welding, ing or other character of work may be performed at ordinarily inconvenient places which are hard to reach and which work may be performed in place ing down or removing the structure to be repaired, and also to provide means whereby these and other objects may be accomplished by a portable and readily handled device of simple and uncomplicated construction which can be readily adjusted and operated, and it comprises an arrangement of parts and combination of members capable of co-acting and cooperating in such a manner as to accomplish the desired result as hereinafter more fully set forth.

The invention comprises specifically the process of and means for utilizing magnetic lines of force for the magnetic coherence of substances to be united or joined and the magnetic spreadin effect of such force for augmenting the we ding or repairing opera- The said magnetic coherence or filling, cutting, shapforce being employed in conjunction with a means such as a reciprocating are induced by an electric current of alternating nature for maintaining a heated or fused condition of the su stances to be joined or united, and also means whereby the material to be fused and joined to the structure to be mended or repaired may be supplied through the combined action of electric fusion and magnetism, which heating or fusing efi'ect may cient and economic mannerto or without takbe accomplished by the employment of alternating, polyphase, or induced currents of electricity of selective character, volume or intensity to produce the desired result.

he invention relates more particularly to that type of electric welding or repairing in which the parts to be joined are relatively fixed and require the application of a metal thereto, or the combining of a. metal therewith, to complete the bonding or uniting of the parts and provides a means whereby the metal electrode is heated and fused by an electric arc of alternating nature and the heated or fused metal is retained in intimate contact with -t'he article to be Welded or repaired at the point to be repaired-by magnetic action induced by a direct electric current separate from the welding current, thereby permitting the article be efficiently welded with a minimum expenditure of energy and with little or no inconvenience to the operator and rendering its utilization in remote and restricted spaces or openings which may permit the use of only one hand of the operator, while at the, same time a means is provided for use and utilization of alternating current which is more generally available and cheaper than direct current for accomplishingthe result.

In the accompanying drawing Figure 1, is a diagrammatic view embodying the features of the invention and Fig. 2 is 21 diagrammatic view showing the application or employment of a polyphase current, such as a three phase current indicated as w, y and 2, and representing the circuits thereof as employed inthe process including the same.

imilar numerals of reference represent corresponding parts in the several views.

In the drawing 1 represents a boiler head with a flue 2 to be welded "Into place the joining of the parts taking place as at 3.

Above the tube 2, or at other convenient location contiguous to electric magnet 4 with winding 5 and core 6 said core being prolonged and forming a convenient handle 8. v

Another electric magnet 9 with winding 10 and core 11 constitutes the welding tool, said core being prolonged to form a convenient handle 12 the provided with a spring socket 13 to securely hold a fusible magnetic element 14 acting as plate 1, is placed an an alternating current electrode and which is adapted to feed and supply the fused metal for welding or repairing.

The relative positions of the various parts as shown in the drawing, permit a-continuous path for the magnetic lines through the above parts be maintained for the successful operation thereof.

- The windings of the electromagnets are in electric connection with a battery 16, conductor 17 and switch 18.

Any convenient source of alternating current may be provided as at 19, said our rent being transformed to suit conditions by a transformer '20, having a controlling switch 23, a current measuring device 24;, and a main switch 25 in circuit therewith.

Conductors 21 and 22 convey the current to and through the cores or the electromagnets, one of which is in electrical and magnetic contact with the plate 1, the other electro-magnet being in electrical and magnetic contact with the joint as at 3 through the medium of-the core 11 the fusing element 14 and the reciprocating are thereby forming'a closed path for the alternating, polyphase, or other electric welding current.

In the operation of the device the electromagnets are energized by the closing of the switch 16 and the placing of one of said magnets in position as shown in the drawing, the other electro-magnet is manipulated by the operator in such a manner as to bring the fusing element in contact with the work and spot to be welded or repaired at which time the switch 25 is closed causing the current to flow through the parts to be welded and the fusing or welding element, the resistance of which is suflicient to cause heating and consequent plastic condition for the efficient welding or repairing of the parts.

The employment of a magnetic condition in the parts to be welded has two functions, first, to provide a readily attached and efficient contact for the passage of the electric current therethrough, and second, to assist the flow of metal around the joint, it being known that a paramagnetic substance tends to fiow away from or with the lines of force.

The accompanying drawing merely illustrates one application of my device,'it being understood that details of construction and the arrangement of parts thereof may be varied so long as the members co-act and cooperate to produce the desired result without changing the substance of or spirit of the invention.

By employing a portable alternating current arc, in con unction with magnetic lines of force induced by a direct current, for

heating and fusing the joining and welding parts and supplying metal thereto through the medium of a reciprocating arc in accordance with the present invention, the operation is performed in a more simple and economical manner and a more perfect and uniform heating is secured by reason of the equal heating of the alternating current electrodes by or through the intervening reciprocating are of the alternating current, and the oxidation of either electrode is pre vented, which is not the case when a direct current arc. is employed which impinges on the anode, superheating the same and 0X1 dizing 1t, and when this single direct curvrent is employed for fusing a metal to be supplied to the object or body to be welded or joined the metal to be supplied which is fused is necessarily the anode and becomes oxidized as such before being supplied. and the point to be welded is also relatively cooled (being the cathode), all of which difficulties and defects in the successful per formance of the welding process as thus carried out in the prior art. depending on the employment of direct current alone augmented by magnetic lines of force, are obviatedv by the employment of an alternating current are in conjunction with magnetic lines of force induced by a separate direct current said are reciprocating between the article to be repaired and an electrode of repair metal forming the subject matter of the present invention.

i It will also be noted that in the present invention the metal supplied to the object welded or joined formsa part of the core of a direct current magnet or plurality thereof and said core is fused and supplied by heat induced by a separate alternating current are which equally heats between the point to be joined and the point offused joining metal supply and provides a uniform supply of metal and the supply of the same to a part to be joined in a selectively heated condition to receive the same and unite therewith and provides a superior non-oxidizing condition of the parts over that resulting from the use of a direct current alone.

The alternating current employed to produce a reciprocating arc. fuse the repair metal electrode, and join, weld, or repair thearticle treated may be derived directly from a generator or through the medium of a transformer or other current altering or changing device, and the reciprocating or fluctuating arc may be altered, directed, or diverted by the action of magnetic lines of force or magnetism derived from any convenient source or position whereby the arc may be contracted 0r elongated as required between the electrode of the repair metal and the article to be repaired, welded, or joined, to accomplish the desired result.
